A total of 396 Thoroughbreds (86 males, 293 females, and 17 geldings) in Kentucky, 1 to 30 years of age, were examined at necropsy for presence of Anoplocephala perfoliata (2 female horses were not examined) in the cecum for lesions of Draschia megastoma in the stomach, during the 1-year period of Mar 1, 1982 through Feb 28, 1983. Prevalence of A perfoliata was 53% and of lesions of D megastoma was 63%. All lesions of D megastoma were partially or entirely in the glandular region of the stomach. Distances of the midpoint of these lesions from the margo plicatus varied from 0 to 290 mm. The center of about 88% of the lesions was within 50 mm of the margo plicatus . Measurements of the size of the lesions, exclusive of masses, indicated that about 95% were less than or equal to 50 mm in diameter. There appeared to be a higher infection rate of lesions of D megastoma in younger horses (81% in 1 to 7 year olds) than in older horses (41% in 8 to 30 year olds) with a few exceptions.
在1982年3月1日至1983年2月28日的1年期间，对肯塔基州的396匹1至30岁的纯种马（86匹公马、293匹母马和17匹去势公马）进行了尸检，检查盲肠中是否存在叶状裸头绦虫（有2匹母马未检查）以及胃中是否存在巨口德拉什线虫的病变。叶状裸头绦虫的患病率为53%，巨口德拉什线虫病变的患病率为63%。所有巨口德拉什线虫的病变部分或全部位于胃的腺区。这些病变中点距胃褶缘的距离为0至290毫米。约88%的病变中心位于距胃褶缘50毫米范围内。对病变大小（不包括肿块）的测量表明，约95%的病变直径小于或等于50毫米。除少数例外情况外，幼龄马（1至7岁的马中为81%）的巨口德拉什线虫病变感染率似乎高于老龄马（8至30岁的马中为41%）。
